This film is summed up nicely by Michael_Elliott, an IMDb reviewer, who wrote the following...
"The impressive silent film starts off with one of the strangest titles cards I've ever read. The film, obviously meant to be played at least a hundred years before 1921, has a title card that tells us current movie goers don't care for costume dramas so they've updated the story to 1921 times. In the film, Rudolph Valentino plays a playboy who has everything he wants in life but his father comes home, obviously upset, and asks him to go stay with his uncle (Ralph Lewis) for a little while. When the playboy reaches his uncle's home he learns that his father has killed himself but his cousin (Alice Terry) is there to comfort him and soon the two fall in love. The problems are just starting because her father is an evil man that only cares about money and will stop at nothing to keep them apart even if one must die. This film is probably best remembered for having a big influence on Greed and that isn't the only reason people should seek this film out. Ingram does a great job in the direction even though the material isn't the strongest that it could have been. I think a little stronger screenplay would have helped the film but there's no doubt that this film contains one of the most memorable scenes in silent history. I wasn't overly thrilled with Terry who I feel somewhat weights the film down with her mediocre performance but Valentino comes off quite strong. The scene stealer is certainly Lewis who turns in a great performance as the wicked father. The evilness of his character certainly jumps off the screen and Lewis does a great job at playing it. The highlight of the film comes towards the end when Lewis is trapped in a room where ghosts of the people his greed as destroyed or killed come to haunt him. The way this scene is shot, with light coming in through a hole in the roof, is extremely well done but it also has a very creepy and eerie tone throughout. This certainly isn't a horror film but this sequence is among the greatest I've seen in any of the silent horrors I've watched."
